In reply to Rich2002:
70m is fine, it's all I had with me last year and I didn't get close to running out of rope in 7 weeks of climbing.
You'll be restricted by the sun. Mornings are spent at the cascade sector, but there aren't many lower grade routes here, though those that are there were pretty good IMO.
Afternoons can be spent elsewhere once the routes are in the shade and there is so much amazing rock to go at in the grades you want!
But you can climb from about 2ish on these areas so you might be restricted by time. I generally got about 5 hours in a day but that was more in August, so with later sunsets you could probably squeeze more in. You can always do a warm up in the sun too to get extra time.
You won't regret going! The local guide is great and about 25 euros in the campsite.
